Abstract
The structure of the title compound has been established by X-ray diffraction analysis. C9H18N2O4, M(r) = 218.25, monoclinic, P2(1)/c a = 9.249(5), b = 10.138(2), c = 12.175(6)Angstrom, beta = 92.21(5)degrees, V = 1141(1)Angstrom(3); Z = 4, D-x = 1.27 g.cm(-3), CuK alpha, radiation (lambda = 1.54178 Angstrom). The final R index is 0.056 for 1860 observed reflections. The data confirm the irans relationship between the two methoxymethyl groups. Large deformation from the synperiplanar conformation and a very long C-N bond are observed in the hydroxamic group. An intramolecular hydrogen bond occurs between the NH and an ether oxygen. Molecules farm dimers by doing intermolecular H-bonds between the carbonyl and the hydroxyl of the hydroxamic acid.
